In this video, we will learn how we can handle errors, validation errors, how we can use pipes, and how we can handle mongoose ID errors in our NestJS API. In my previous video, I created a complete CRUD Library API.
In this video, we will continue with that project and add the error handling and validations in this API in simple few steps.

Welcome

[@KU10S]

if its optional you don't want to put IsString() there.

[@codingwithabbas]

If user enter any input then it should be string, otherwise user can leave it as it is optional.

[@KU10S]

Yes. But optional means that u can choose to give it. If u add string to it then its not optional.

[@alexiscano4167]

@@KU10S Is optional to give it, but if you give it, should be string, is that simple.
